Description
DARWIN is a proposed next-generation dark matter observatory that aims to detect Weakly Interacting Massive Particles (WIMPs) using 40t of instrumented liquid xenon. Due to its large dimensions together with the technical and scientific challenges involved, Xenoscope, a full-scale vertical demonstrator, was built to test and refine the necessary technologies. This prototype was constructed to demonstrate electron drift in liquid xenon over a 2.6-m distance, thus serving as a key R&D component for the DARWIN. Calibrations are needed to estimate the electron lifetime in liquid xenon. In this talk, I will present an overview of how radioactive sources are used in the calibration phase of Xenoscope.
